A port of Anarch for bare metal Raspberry Pi (with Circle).
This is a port of the fps Anarch to raspberry pi in bare metal mode, that is, without operating system (the rpi boots straight into the game). This is possible thanks to Circle.
Actually the game is playable with keyboard. Keys are mapped to Z, X, A and the cursor. Tested on RPi 3.
Missing feature/TODO:
- no sound
- no mouse
- no save/load
- no gamepad
All these should be easy to implement (except maybe sound).
You need an ARM toolchain and a linux machine.
PATH=/path/to/gcc-arm-none-eabi-9-2020-q2-update/bin:$PATH put your path to the arm toolchain bin folder
git clone https://github.com/rsta2/circle.git
git clone https://gitlab.com/drummyfish/anarch.git
nano circle/Rules.mk Set RASPPI to your raspberry board version (like 3)
cd circle
./makeall clean
./makeall
cd ../anarch-baremetalpi/
make
cd ../circle/boot
make
copy all file under circle/boot (read the README there, expecially for RPi4) to an SD card
copy anarch-baremetalpi/kernel*.img to the SD card
now put the SD card into the RPi and start it.
